Eyes down for the latest YouTube baby sensation. And just how adorable is this giggling bubba? The tot - Emerson - goes from being scared witless to having a fit of uncontrollable giggles as his mum blows her nose off camera.

The video has gone viral, attracting more than two million views in just two days.

Emerson's mum says the five-and-a-half month old baby isn't quite sure how to react when she reaches for a handkerchief: 'Emerson isn't sure what to think when I blow my nose. Sometimes he's terrified, then he can't stop laughing,' she says.

What do you think? Funny and cute, or mean to scare such a young child?
